The standard rap on P.K. Dick can be read here. If you are of a certain age you read Dick in short story form in pulp SF magazines like “Amazing Stories” and most importantly the novel “Do Androids Dream of Electric Sheep?” (1968) and the now lesser known novel “The Man in the High Castle” (1962).

Seven wives and repeated brushes with alcohol and methamphetamine abuse were ghosts which haunted his life and writing. According to the official web site: In February and March 1974, Dick experienced a series of visions and auditions including an information-rich “pink light” beam that transmitted directly into his consciousness.
This experience was documented by R. Crumb in the 1986 Comix: Weirdo No. 17 .
